“…Conilon genotypes in areas of higher altitude increased considerably in recent years. This intended to couple Conilon's high productivity and vigour with the possibility of improved coffee bean quality at a higher altitude, as found for C. arabica (Abreu et al, 2012), in order to comply with an increasing consumer's demand.…”

Low temperature and water deficit are the major climatic limitations for the coffee plant, affecting metabolic performance, development and yield. This work aims at evaluating the physiological responses of Coffea spp. genotypes grown in high-altitude (734 m) areas under field conditions, using 3-to-4-year-old plants of C. arabica cv. Catucaí Vermelho (785/15) and C. canephora cv. Encapa 8111 Clone 02 (02V). Predawn leaf potential water, net photosynthesis, stomatal conductance, internal-to-external CO 2 concentration ratio, and chlorophyll a fluorescence (JIP Test) values were assessed in March (adequate temperature and water availability conditions), July (suboptimal temperature) and October (low water availability). The growth of orthotropic and plagiotropic branches and the number of nodes were monitored monthly for 13 months, whereas two years yield was evaluated. Low temperatures (July) affected photosynthesis of both genotypes, although 785/15 showed smaller after-effects by October and unaltered values of almost all fluorescence parameters throughout the year (reflecting a high functional stability), and a higher number of nodes with a potential positive impact on yield. The 02V plants also kept relevant photochemical functioning, maintaining the values of several JIP Test parameters, a branch growth higher than 785/15, and a similar yield to that found for 02V in some lowaltitude areas. Therefore, C. canephora was able to cope with moderate low temperature and water deficit constraints that prevail in areas of higher altitudes for part of the year, while maintaining yield performance. Therefore, this genotype shows considerable potential to be cultivated at higher altitudes than what is traditionally considered adequate for C. canephora.

“…Most of these studies have aimed to distinguish (or classify) the origins − between arabica ( Coffea arabica L.) and robusta ( Coffea canephora P.) − or between defective beans and nondefective beans , for compound-targeted measurements or nontargeted measurements coupled with multivariate statistical analyses. Only a few studies have reported on the correlation between metabolites and beverage quality or on the correlation between metabolites and maturity levels, − which influence the quality. However, these studies were performed for specific targeted compounds (the major constituents in green beans), such as caffeine, , chlorogenic acid, − and trigonelline. , Therefore, the relationship between metabolites and quality remains to be explored.…”

The quality of coffee green beans is generally evaluated by the sensory cupping test, rather than by chemical compound-based criteria. In this study, we examined the relationship between metabolites and cupping scores for 36 varieties of beans, using a nontargeted LC-MS-based metabolic profiling technique. The cupping score was precisely predicted with the metabolic information measured using LC-MS. Two markers that strongly correlated with high cupping scores were determined to be isomers of 3-methylbutanoyl disaccharides (3MDs; 0.01-0.035 g/kg of beans) by spectroscopic analyses after purification, and one of them was a novel structure. Further, both the 3MDs were determined to be precursors of 3-methylbutanoic acid that enhance the quality of coffee. The applicability of 3MDs as universal quality indicators was validated with another sample set. It was concluded that 3MDs are the causative metabolites determining beverage quality and can be utilized for green bean selection and as key compounds for improving the beverage quality.

“…Such conditions can support the biosynthesis of substances related to aroma and flavor characteristics [13]. The higher the growing place, the value of the total score of Arabica coffee quality tends to increase [14], [15]. The increase in the total score is also associated with changes in other climatic characteristics, such as mean temperature and precipitation rate [15].…”

The type of coffee affects the compounds in it, the environment, and the soil. One of the areas in West Sumatera where a Coffee Producer is Solok Regency. The kind of coffee that is cultivated in Solok is Arabica coffee. The height of the planting point has an influence on the taste, so Solok Arabica coffee has a different taste from the flavors of other Arabica coffees that are widely spread throughout Indonesia. This study aims to determine the compounds contained in Solok Arabica coffee, which was roasted at 200 o C for 10 minutes. The compound detection in Solok Arabica coffee was carried out using gas chromatography-mass spectrometry (GC-MS). The results of GC-MS analysis detected 25 compounds in Solok Arabica coffee at 200 o C for 10 minutes, and 4 of them were detected in large quantities, namely pyridine, caffeine, n-hexadecanoic acid, and butyl 9,12-octadecadienoate with amounts between 70-97 m / z. Pyridine is a benzene derivative by replacing CH groups with N atoms, which are toxic to humans because they can cause nausea, vomiting, headache, dizziness, and irritation when in contact with the skin. Caffeine is the main bioactive component of the purine ring system in coffee. The sensory test method used to determine the typical Arabica Coffee of "Ranah Minang" is cupping to assess the taste of the coffee. n-hexadecanoic acid is a saturated fatty acid with antioxidant, hypocholesterolemic, nematicide, anti-androgenic, hemolytic, pesticide, lubricant, 5-alpha reductase inhibitor, antipsychotic, and anti-inflammatory activity.
